With his friend and fellow Schakal, Richard Berna, he kidnapped a young woman, Donna Reynolds. When Nick and Hank came to his house, he was burning a photograph of her in his fireplace. When Nick went to check the fireplace, the picture had been burned too much, and they were forced to let him go after arresting him. Ryan Smulson then showed up at Adrian's house and proceeded to torture him into disclosing where Donna was being kept. He then killed Adrian after branding him several times with the mark of the Endezeichen Grimm (a Sterbestunde G) onto his body.
